Abstract
The utility model discloses a connecting structure of pile foundation reinforcement cage reinforcing steel bars. The connecting structure comprises a first section reinforcement cage (1), a second section reinforcement cage (2) as well as a sleeve (5) with inner threads inside, wherein the first section reinforcement cage (1) comprises a plurality of first circle-shaped longitudinal reinforcing steel bars (3); the second section reinforcement cage (2) comprises a plurality of second circle-shaped longitudinal reinforcing steel bars (4); outer threads are formed at two ends of both the first longitudinal reinforcing steel bars (3) and the second longitudinal reinforcing steel bars (4); two ends of the sleeve (5) are respectively in threaded connection with the first longitudinal reinforcing steel bars (3) and the second longitudinal reinforcing steel bars (4). The connecting structure is convenient and rapid to install, high in structural stability, short in construction period and high in quality controllability, and moreover butt joint connectors of the reinforcement cages are continuous and high in precision.
Description
Technical field
The utility model relates to the syndeton of adjacent segment reinforcing cage, specifically a kind of syndeton of pile foundation steel bar cage reinforcing bar.
Background technology
Development along with bridge technology, bridge across footpath progressively increases greatly, major diameter, overlength pile foundation steel bar cage are more and more employed in design, the features such as pile foundation steel bar cage also has that diameter is large thereupon, Heavy Weight, length is long, bar splice is many, merogenesis docks often.Because the on-the-spot installation period of reinforcing cage of major diameter, overlength pile foundation is long, therefore when assembling pile foundation steel bar cage, reinforcing cage precipitates too much and the problem that has hidden danger of quality at the bottom of easily producing collapse hole, hole, is therefore necessary to improve.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art part, and a kind of syndeton of pile foundation steel bar cage reinforcing bar is provided.
To achieve these goals, the technical solution of the utility model is: the syndeton of pile foundation steel bar cage reinforcing bar, comprise the first sections reinforcing cage and the second sections reinforcing cage, described the first sections reinforcing cage comprises some the first longitudinal reinforcements that are round, described the second sections reinforcing cage comprises some the second longitudinal reinforcements that are round, it is characterized in that: also comprise that inside establishes female sleeve, the two ends of described the first longitudinal reinforcement and the second longitudinal reinforcement are equipped with external screw thread, and the two ends of described sleeve are threaded with the first longitudinal reinforcement and the second longitudinal reinforcement respectively.
The shell of described sleeve is provided with rolling decorative pattern.
The cross section of described sleeve is rectangle, regular hexagon or circle.
In technique scheme, owing to being connected by sleeve between the first longitudinal reinforcement and the second longitudinal reinforcement, make assembling the first longitudinal reinforcement and the second longitudinal reinforcement that staff not only can be convenient, and improved the assembly precision between the first longitudinal reinforcement and the second longitudinal reinforcement, thereby improved the structural stability of pile foundation steel bar cage.
Compared with prior art, its advantage is the utility model:
1. because reinforcing cage is that batch production is prefabricated continuously in precasting yard, short construction period, quality controllability is strong;
2. because the utility model employing is segmented prefabricated, utilize last sections for fixed form, banjo fixing butt jointing is continuous, and banjo fixing butt jointing precision is high;
3. reinforcing bar adopts sleeve to connect, and technique is advanced, quick and easy for installation.
To sum up, the utility model is convenient and swift when mounted, and structural stability is higher, and not only short construction period, quality controllability are strong, and the banjo fixing butt jointing of reinforcing cage is continuous, and banjo fixing butt jointing precision is high.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
1-the first sections reinforcing cage in figure, 2-the second sections reinforcing cage, 3-the first longitudinal reinforcement, 4-the second longitudinal reinforcement, 5-sleeve.
The specific embodiment
Below in conjunction with accompanying drawing, describe performance of the present utility model in detail, but they do not form to restriction of the present utility model, only for example.By explanation, make advantage of the present utility model more know and easily understand simultaneously.
Consult accompanying drawing known: the syndeton of pile foundation steel bar cage reinforcing bar, comprise the first sections reinforcing cage 1 and the second sections reinforcing cage 2, described the first sections reinforcing cage 1 comprises some the first longitudinal reinforcements 3 that are round, described the second sections reinforcing cage 2 comprises some the second longitudinal reinforcements 4 that are round, it is characterized in that: also comprise that inside establishes female sleeve 5, the two ends of described the first longitudinal reinforcement 3 and the second longitudinal reinforcement 4 are equipped with external screw thread, and the two ends of described sleeve 5 are threaded with the first longitudinal reinforcement 3 and the second longitudinal reinforcement 4 respectively.
The shell of described sleeve 5 is provided with rolling decorative pattern.
The cross section of described sleeve 5 is rectangle, regular hexagon or circle.
Owing to being connected by sleeve 5 between the first longitudinal reinforcement 3 and the second longitudinal reinforcement 4, thereby make assembling the first longitudinal reinforcement and the second longitudinal reinforcement that staff not only can be convenient, and improved the assembly precision between the first longitudinal reinforcement and the second longitudinal reinforcement.
The utility model is applicable to the long L >=27m of stake, and the φ >=1m pile foundation steel bar cage construction of stake footpath, as borehole filling pile cage of reinforcement construction.
In practical work process, when assembling pile foundation steel bar cage described in the utility model, can below reinforcing cage, place a mould bases.Pile foundation steel bar cage is colligation on mould bases, utilizes front two sections of reinforcing cages as section of foundation during assembling, prefabricated next sections, and cyclic process, thus guarantee two sections of connection precision between reinforcing bar.
In practical work process, after reinforcing cage is prefabricated with groove, carry out the installation of sound detecting pipe.The merogenesis length of sound detecting pipe is consistent with the merogenesis situation of reinforcing cage.Between sound detecting pipe and reinforcing cage, every 2m left and right, with " U " type card, be fixed.Stopper plug sealing for detector tube upper port, lower end bulkhead welded seal, forbids cement paste or foreign material to enter in pipe, guarantee filling concrete after pipeline unimpeded.
In practical work process, reinforcing cage should be noted that following item when depositing and transport:
1. reinforcing cage leaves on smooth, dry place in order, faces mutually that two two reinforcing bars corresponding to reinforcing bar sections are painted mark so that field joint hangs up sign board on each reinforcing bar sections simultaneously.
2. after reinforcing cage jointing splits, reinforcing steel bars exposed screw thread must adopt protective sleeve protection, prevents screw thread damage.
3. reinforcing cage adopts special hanger to lift transhipment, prevents distortion.
In practical work process, reinforcing cage is installed and is adopted gantry crane, crawler crane or other loop wheel machine merogenesis to transfer, and adopts mechanical connection spreading reinforcing cage.Reinforcing cage is located its top after transferring and putting in place, reinforcing cage skew, floating while preventing pour concrete.
Other unaccounted part all belongs to prior art.
